Is there a filter to best express users' disdain for the latest update to Snapchat?

Recently, the messaging app popular among younger smartphone owners launched a major redesign, aimed at drawing a line between communications with friends and content from publishers, the produced short, text-heavy videos from outlets like Vice or Cosmopolitan.

Based on reactions from Snapchat users, many hate it.

The app currently carries an average rating of 1.9 out of 5 stars on Apple's App Store, although it remains the most popular app in the Photo & Video category.

The most recent user reviews complain the update is a big reason for the lower rating.

"I absolutely hate the update," reads one review from user Piethrower3000. "Everything is so messy and disorganized."

Another issue bugging users: Snapchat quietly rolled out the changes as opposed to releasing them as a more formal update users could opt to download.

In November, Snapchat revealed details of its update, which includes moving all chats and stories from friends to the same spot when you swipe left. Swiping right brings up the Discover tab, where you can view content from publishers.

"Updates as big as this one can take a little getting used to, but we hope the community will enjoy it once they settle in," said parent company Snap in a statement.

The goal of the update was to clearly separate messages users send to friends from commercially produced content. That blurring of professional and personal, a hallmark of modern social networks, also had a downside— pressuring users to put on a performance.

"One of the complaints we’ve heard about social media is that photos and videos from your friends are mixed in with content from publishers, creators and influencers," said Snap CEO Evan Spiegel in a video released when the changes were revealed. "But your friends aren’t content. They’re relationships."

Snapchat faces increased pressure from photo sharing app Instagram, which has incorporated several features from its rival such as the ability to post Stories that disappear after a set period of time.

According to research firm eMarketer, Instagram users will total 104.7 million users this year in the U.S., compared to 86.5 million users for Snapchat.
